How long before resin fully cures?
Craft Resin's cure time is about 24 hours (depending on the thickness of your project). This is the time the resin and hardener mix goes through the chemical reaction to form a solid. After 24 hours it still might not be completely solid, and can be slightly flexible.
Why is my resin bendy after 48 hours?
In most cases, the reason you have resin that bends is due to the fact that the resin needs more time to cure. After 24 hours, ArtResin will be at a 95% solidity rate. If you attempt to curve or move the resin before that 24 hour mark, the resin will likely bend.

How long should epoxy cure before sanding?

How do you speed up epoxy cure?
Generally, epoxy cures faster when the air temperature is warmer. Exothermic heat is produced by the chemical reaction that cures epoxy. The amount of heat produced depends on the thickness or exposed surface area of mixed epoxy. In a thicker mass, more heat is retained, causing a faster reaction and more heat.
Can you dry resin with a hair dryer?
Resin curing Using Hair or Blow Dryer You can use a blow dryer or hair dryer to dry your resin art fast. To do this, simply plug in the dryer and blow it directly onto your resin art. But be cautious to not blow too hard and too warm.
